摘要：A method for controlling the blending of blend stocks (10a-10n) having boili ng points less than 350 .degree.C into blend products (24) with feedstocks and products with boiling points less than 350 .degree.C. Th e method comprises selecting one or more performance properties of blend stocks (10a-10n), and creating a training set from reference sample s (46) which contain characteristic molecular species present in the blend stocks (10a-10n). The reference samples (46) are subject to a GC/MS analyzer (60), wherein the collinear data generated is treated by multivariate correlation methods. The training set produces coefficients which are multiplied by the matrix generated from the GC/MS analyzer (60) of unknown blend stocks (10a-10n) to produce a predicted value for the chemical, performance, perceptual, physical property or groups of properties selected.
